Columbia scientists recently visited the Caribbean island of Barbados, whose fossilized coral reefs contain an exquisite record of how the ocean has risen and fallen in the past.

To help predict the future of sea level rise, scientists are studying ancient corals on the island of Barbados.
Tightly packed sediments help the Cascadia Subduction Zone generate large earthquakes, and could boost its ability to trigger a large tsunami.
An interdisciplinary team of scientists has discovered that, contrary to general scientific belief, iron in nondissolved particle form can stimulate phytoplankton growth, and that the chemical form that particulate iron takes is critical to ocean photosynthesis.
The oceans of the world are a vast unexploited source of clean, reliable and predictable renewable energy. Could this energy help replace fossil fuels and be a solution to climate change?
More than 85 percent of the ocean floor remains unmapped, leaving us in the dark about much of the earth’s topography. A global, non-profit effort will try to remedy that, and influence everything from climate research and weather prediction to mineral resource exploration and fisheries.
Lamont-Doherty Earth Observatory scientists Ryan Abernathey and Richard Seager are investigating how processes in the ocean create extreme weather and climate conditions over land.
It’s midnight on the ship, and the labs are filled with scientists busy examining samples. Two of them just got back from a trip to the seafloor, and the excitement is palpable.
Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized.
Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of carbon-capturing algae, but a new study shows that the excess iron had little to no effect.
